Fan Casting Power Rangers (2007)

In the Cenozoic era, six interplanetary warriors, the Power Rangers, are tasked with protecting life on Earth and the Zeo Crystal. The Green Ranger, Rita Repulsa, betrays them and plans to dominate the universe by killing her team. The Red Ranger, Zordon, survives Rita's attack and hides five of the Rangers' power source, the Power Coins (including his own). He orders Alpha 5, his robotic assistant, to perform a meteor strike that kills him, the dinosaurs, and sends Rita to the bottom of the sea, foiling her scheme.
